For reasons, you might want your Jenkins Multibranch Pipeline jobs to do a different thing depending on which branch is being built.
Fortunately, the multibranch plugin provides us with a built-in variable BRANCH_NAME, which we can use to figure out which branch we are currently building.
In such scenarios, it’s not a bad idea to create a minimal Jenkinsfile at the repo root that contains just enough logic to figure out which branch we are on, and then call another groovy script that contains the actual build definition:
This is a short illustration of using a local installation of Jenkins on Windows to build an SSDT project from a local git repo and deploy it to a SQL Server on the same machine.
This is probably useful for a quick demonstration or to understand how the various moving parts fit together, but possibly less applicable to “Real Life” production environments.
There are no build agents and no git remotes; all the action takes place on the Jenkins master, and the git repo is local to the same machine.
How SSDT can help with restoring a SQL Server database to “just before that last deployment” For as long as I can remember, SSDT and its predecessors have had the option to “Back up database before deployment”, currently available in the “Advanced Publish Settings” dialog, among other places. Regrettably, I’ve never really had much use for this particular option. Whilst restoring from backup might be a valid strategy for recovering from some kinds of deployment disaster, this could add a great deal of time to the deployment process, assuming a database of non-trivial size.
For reasons, I recently found myself in a scenario where I needed to test whether a branch existed before checking it out, and resorting to a sensible default - such as checking out master, if it didn’t. From the command line, this is a simple matter of git branch -l | grep myBranch, but I needed to do this from the context of a Jenkins pipeline job.
Preliminaries For simplicity, I’m creating a local repo I can point my Jenkins job at, right inside the JENKINS_HOME folder.
